LOOSE-LEAF BINDER.

Specification of Letters Patent.

Patented Dec. 30, 1913.

To all whom it may concern Be it known that I, JOHN G. MAGIN, of Rochester, in the county of Monroe and State of New York, have invented a new and useful Improvement in Loose-Leaf Binders, which improvement is fully set forth in the following specification and shown in the accompanying drawings.

The present invention relates to loose leaf binders and an object of the same is to improve the hinges of the covers in order to obtain greater durability and cheapness of construction.

Another object of the invention is to provide, in that type of loose leaf binder having a. removable transfer member, means for supporting the transfer member in the binder when said transfer member is removed from its normal position.

To these and other ends the invention consists in certain parts and combinations of parts all of which will be hereinafter described, the novel features being pointed out in the appended claims.

In the drawings: Figure 1 is a perspective view of the binder in open position, with the leaves removed and the transfer member removed from its normal position but supported on the binder; Figs. 2 and 3 are plan views of the two hinge connections; Fig. 4 is a sectional view of the loose leaf binder, transverse of the hinge connections; and Figs. 5, 6 and 7 are detail perspective views of portions of one of the hinge connections.

Referring more particularly to the drawings, a and 1) indicate two cover members hinged, preferably in a manner to be described, to two intermediate or connecting members 0 and d which, in turn, are hinged to a back piece 6, the intermediate connecting members carrying the binding means for the leaves. The binding means, in this instance, comprises a strip of metal 1 forming a supporting member for one or more posts or impaling projections 2 projecting upwardly therefrom in parallel relation'and preferably having anoval cross section, their upper ends being provided with notches 3 forming shoulders for engagement by retaining means carried by the intermediate or connecting member 0 of the cover a. In this instance, the intermediate member carrying the retaining means embodies two strips of material 4 and 5 substantially U- shape 1n cross section and one housed within the other to provide a casing for a retaining or latch bar 6. The latter may be slidably or otherwise arranged within said casing and moved in one direction by a spring 7 and in the other direction through the means of a finger piece 8 projecting from one end of the retaining casing, said bar having openings therein to fit over the upper ends of the posts or impaling projections 2 and engage in the notches 3 as is common in this art.

The leaves are formed with openings corresponding to the cross sections of the posts 2 in order to fit over said posts. They are also provided with openings for receiving the projections or posts 9 on the transfer member which may comprise a bar 10 provided with openings 11 adapted to fit over the upper ends of the posts 2 and to be; held in position thereon by the retaining means before described.

A feature of this invention is the construction of the hinges between the cover members a and b and the intermediate connecting members 0 and d. Both of the cover members are preferably made from two sheets of card board, 12 and 13, having a suitable covering 1 1 and between these two sheets of card board of each cover is secured one of the hinge members which, prefera-bly, comprises a single piece of metal bent upon itself to provide two leaves 15 and 16 connected by a bead or tubular portion 17, said tubular portion being cut at intervals to provide recesses or notches 18. Through this tubular portion 17 extends a hinge pintle or rod 19 which is exposed at the notched portions 18 for engagement by portions on the intermediate or connecting members a and (Z.

On the member 0 are provided two straps of sheet metal, each bent upon itself to pro vide two abutting portions 20 and 21 and a tubular portion connecting the portions 20 and 21 and surrounding the pintle 19. The portions 20 and 21 of each strap are extended through a notch in the member 4 and an opening 24 in a flange of the member 5, being riveted to the inside of the latter at 32, so that the tubular portion 22 projects from one side of the member 4.

On the intermediate member cl are providedztwo straps each beat. iateimeaiaa er.

lying on opposite sides of the bar 1 and riveted at 26 thereto, a filling piece 24 being introduced between the arms 25 to confine,

the pivot pin 19. The intermediate or connecting members 0 and d and thebacking piece 6 have common covering 27 which, at 28, serves as a hinge between the aforesaid parts, and also covers the exposed portions of the hinge straps. Thecover-ings 14, of covers a and b, are extendedover the tubular portions 17 and in this way the hinges are concealed.

In loose-leaf binders having removable transfer members with 'impalin'g projections, it has been found that, when there are but a few loose leaves 'on tlie "transfer member, the latter is liable to topple over owing to the fact that the bar 10 'is not sufficiently wide to provide a suitable base, This has been found to be particularly disadvantageous when the loose-leaf binder is used in connection with book typewriting machines where the leaves are transferred, one at a time, onto the transfer member. To overcome this disadvantage, there has been provided, on the binder, suitablemeans for supporting the transfer member when the latter is removed from the impaling posts 2, such support being, preferably, so located'tha't the undermost leaf thereon rests almost entirely upon one of the cover members.

To the above end, there are preferably'arranged, on the inner face of thecover member a, suitable supporting devices'for holding the transfer member to the binder. These supporting members are in the 'form of spring clips each preferably formed from a single piece of metal bent to provide a L!- shaped portion '29 lying in close proximity to the hinge of the cover member a and opening toward the free end of said covermember, one arm of the clip being free and having a retaining nose 30, andthe other arm having an attaching portion 31secu red to the cover member a, said attaching portion being oifset at 32 and lying parallel with the cover member which is provided with a pocket at 33 so that the attaching portion may be' countersunk in the cover a and'concealed by the covering 14. The supporting members may be secured to the hinge member of the cover a by screws 343 and the hinge member may be reinforced at 35 by ablock in order to provide an anchor for the screws 34.

A loose-leaf binder constructed in accordance with this invention is provided with hinges which are durable in use and coonomical to manufacture. The transfer member is adapted to be so supported that the leaves thereon may'lle upon one of the cover members while the leaves on the impalin gposlts lie fan the ,other covermember Without interfering with the assembling of the leaves onthe twomembers.

What I claim as my invention and desire to secure by Letters Patent is:

1. A member for a hinged connection for a loose leaf binder comprising two parts forming a casing between them, one of said parts being of U shape in cross section and having an opening on one side, and a strap formed of a single piece of material bent upon itself to form a tubular portion and a portion which extends through the opening in the'U-shaped member and is secured to the interior thereof. V 7

2. A member for a hinged'corrnection for loose leaf binders comprising a casing formed of two pieces, U-sh'aped in cross section,'a'nd fittingone within the other, -one of said pieces being notched 'atone edgeai d the other of said pieces having an opening in its side, a strap formed ofa single piece of material bent upon itself to provide a tubular portion and a portion which extends through "the notched portion and the opening of the two U-s'haped members and is secured within one ofsaid members.
